Abstract

Saussurea pseudogracilis Kitam. is characterized by its slender leaves, small involucre and small number of involucral bracts compared to Saussurea gracilis Maxim. But some taxonomists insist that it is hard distinguih S. pseudogracilis from S. pseudogracilis. We tried to discern taxonomic identification of S. pseudogracilis by measuring and analyzing 45 qualitative characters and 42 quantitative characters on 165 specimen. S. pseudograilis was not distinguished from S. gracilis not only by qualitative characters but also by quantitative characters even on statistical analysis(PCA). Therefore, S. pseudogracilis is not independent taxonomic species and it is proper to consider S. pseudogracilis as a synonym of S. gracilis.

가야산은분취(Saussurea pseudogracilis Kitam.)는 길고 좁은 잎, 작은 총포, 적은 총포편 열수에 의해 유사종인 은분취(S. gracilis Maxim.)로부터 구별되고 있다. 그러나 가야산은분취와 은분취를 구별할 수 없다고 주장하는 견해도 있다. 가야산은분취의 분류학적 실체를 확인하기 위해 45개의 정성형질과 42개의 정량형질을 측정 및 분석하였다. 정성형질은 물론 정량형질에 대한 다변량분석(PCA)에서도 가야산은분취와 은분취를 구별할 수 없었다. 가야산은분취는 분류학적으로 독립된 종이 아니며 은분취의 이명으로 처리함이 타당하다.
